Renkforce MP 2000 MP-2000 数据表

With this power amplifier, you purchased a product built to the state of the art and operationally safe. Ne-

vertheless, problems or errors may occur. The following contains descriptions for the removal of possible

interferences.

No function, the device cannot be switched on:
•  Is the mains plug connected to the mains socket?
•  Is the amplifier’s fuse defective?
•  Check the mains socket. Is it properly supplied with current?

No sound is audible:
•  Are the LEVEL (2) volume controls of the amplifier set to minimum (left stop)?
•  Are audio source and speakers connected correctly?
•  Is the audio source switched on and its volume control not set to minimum?

One channel does not work:
•  Are the inputs and speakers connected correctly? Has a plug come loose?
•  Is the audio source’s balance control in the centre position?
•  Is one of the LEVEL (2) volume controls of the amplifier set to minimum (left stop)?

The sound is distorted:
•  The level at the mixer is set incorrectly/the amplifier input is overmodulated.
•  The volume at the amplifier is set too high.

A humming distortion can be heard:
•  Are the signal cables from the audio source okay?
•  There is a ground hum between the connected devices. Connect the signal ground with special earth-

insulated cables.

Playback has no bass share:
•  Is one of the speakers connected with the polarity reversed?
